100+100*2%=x-10%x+（100-x）+（100-x）*5%上面的式子怎么算?

（X+X)+(X-X)+(X*X)+(X/X)=100 100/x+1/2=150/(x+10) x=? 100(3x-1)+10x+(2x+1)=100(2x+1)+10x+(3x+1)+99 100(3x-1)+10x+(2x+1)=100(2x+1)+10x+(3x-1)+99 100（3X-1)+10X+(2X+1)=100(2X+1)+10X+(3X-1)+99 1/X(X+1)+1/(X+1)(X+2)+1/(X+2)(X+3).+1/(X+99)(X+100)= 100(X - 2) + 10X + 2X = 100*2X + 10X + X - 2 - 495 解方程：2x+4x+6x...+100x=1-(x+3x+5x+...+99x) 1X+2X+3X…+98X+99X+100X=50500X X等于多少? 1x+2x+3x+4x+5x+6x+7x…+99x=100 100×2x+10x+3x+216=100×3x+10×2x+x 设函数f(x)=(x-1)(x-2)...(x-100)(x>100),求F'(X) f(x)=x(x-1)(x-2)…(x-99)(x-100),求f'(100) 100-2x+5x=120(x+3)×5-2x=30100-(4x+1)-(4x+1)=204x+8=6x-10 100-2x+5x=120(x+3)×5-2x=30100-(4x+1)-(4x+1)=204x+8=6x-10 x(x-1)(x-2)...(x-99)(x-100) x-2=(104-x)+2 6x-59=10x-75 (x+10)+(x-15)=280-x4（x-62)=x-38 60x-40=(60+20)*(x-5) 32x+32*0.5-25x+64x=24x+496-49x x+15=3*(109-x ) 5(3x-1.4)=2(6x-0.5) 3(x+0.9)=5(x-1.7) 13x-4(2x+5)=17(x-2)-4(2x-1) (13x+8)/3=5x-1x-60=2[(3561-x)+100]+1 (x+9)+12=2[(x-9)-1 已知x^4+x^3+x^3+x^2+x^1+1=0,求x^100+x^99+x^98+x^97+x^96的值
